I have my antenna installed (Terk HDTVo) and when I connect directly to my tv I receive local analog stations, so I at least know it works. Now I'm having problems when I connect to the 8VSB port on the 921 receiver. I do a scan for both ATV and DTV channels and it continues to say processing, but the yellow channel bar never actually moves. Can anyone please help me?! I want to get the major networks in HD and should be within the necessary range. Also, the HD channels end in .1, so how do I get the .1 extension entered?
